specific Embodiment approach 1

[0017] Specific implementation mode 1: In this implementation mode, a method for preparing up-conversion red-emitting indium sulfide is specifically completed according to the following steps:

[0018] 1. Weigh 75-85 parts of InCl according to the mass parts 3 , 10 to 15 parts of ErCl 3 and 8 to 12 parts of TmCl 3 , simultaneously according to the ratio of the sum of the amount of substance of In, Er and Tm and the amount of substance of thiourea is 1: 1.5, takes by weighing thiourea;

[0019] 2. Weigh the InCl in step 1 3 , ErCl 3 , TmCl 3 and thiourea are packed into a lined polytetrafluoroethylene reactor to obtain a mixed solution;

[0020] 3. Magnetically stir the mixed solution in step 2 for 28-32 minutes, then add deionized water until the filling degree of the reactor reaches 60%, and seal the reactor;

[0021] 4. React the reaction kettle in step 3 at a temperature of 164°C to 166°C for 24 hours, then naturally cool to room temperature, and take out the reactant...

specific Embodiment approach 2

[0024] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that in step 1, 72 to 74 parts of InCl are weighed according to the number of parts by mass. 3 , 13 to 14 parts of ErCl 3 and 10 parts TmCl 3 . Others are the same as in the first embodiment.

specific Embodiment approach 3

[0025] Embodiment 3: This embodiment is different from Embodiment 1 in that: in step 3, stir magnetically for 30 minutes. Others are the same as in the first embodiment.

Abstract

The invention discloses a method for preparing up-conversion red light-emitting indium sulfide, relates to the technical field of up-conversion light emitting, and aims to solve the problems of complexity of a preparation process and high risk of an existing method. The method comprises the following steps of 1, weighing; 2, mixing; 3, stirring; 4, reaction; 5, washing and drying. According to the method, the preparation process is implemented under a low-temperature condition, the method is mild in reaction, free of risk and easy to operate, and up-conversion light-emitting characteristics of rare earth elements are effectively utilized. The method is used for preparing the up-conversion red light-emitting indium sulfide.

Description

technical field [0001] The invention relates to the technical field of up-conversion luminescence. Background technique [0002] Doping other elements or causing defects in the semiconductor lattice is the main means of controlling the properties of semiconductor materials in modern semiconductor technology. At the same time, doping also has a great impact on the optical, luminescent and magnetic properties of semiconductors and other physical properties. Therefore, controlling and understanding the doping behavior of nano-semiconductors is of great significance for the application of such materials in electronics and photonics technology. The introduction of rare earth elements can realize the manipulation of the luminescent properties of semiconductor nanocrystals, making it possible to expand the spectral properties of semiconductor materials. For sulfide-based luminescent materials, such as ZnS, due to the large radius of the doped rare earth ions (85-l05pm), it is easy...
